Uwe Hermann 2451a20ff5 fs9721: Factor out common code from serial-dmm.
These functions are FS9721 specific (and DMM specific), and can be used
from various drivers (e.g. serial-dmm or uni-t-dmm or possibly others).

Uwe Hermann 913abe8321 fs9922: Use common DMM API.
Use the same functions and structs as the other DMM protocol parsers
in hardware/common/dmm. Among other things, this allows the functions
to be used from drivers in a generic way, e.g. in serial-dmm, uni-t-dmm,
and possibly other drivers.

Alexandru Gagniuc 33c6e4c5a4 session: Make sr_session_stop thread-safe
With the sigrok session running in a worker thread, if sr_session_stop is called
from another thread, it shuts down the pollfds used by the hardware drivers,
without ensuring that the sigrok event loop is no longer using those pollfds.

On the demo driver, this involves shutting down the GIOChannels, causing a
segfault when the sigrok event loop tries to use them. This is evident when
using the Stop button in PulseView, while the session is running.

This isn't a problem with just the demo driver; any driver's resources may be
freed by sr_session_stop concurrently with the sigrok session running.

To solve this problem, we don't touch the session itself in sr_session_stop().
Instead, we mark it for decommissioning and return. The session polls this flag,
and shuts itself down when requested.

This fixes bug 4.

Bert Vermeulen 722db131a4 Add sr_config_free()
Due to struct sr_config now containing a GVariant, this needs to be
cleaned up after use properly. This is a helper function for that.

Bert Vermeulen bc1c2f001a Use GVariant for sr_config_*() functions
sr_config_get() provides a GVariant owned by the caller, so it must be
released with g_variant_unref() when done.

sr_config_set() takes a GVariant from the caller which may be floating;
it will be properly sunk and release after use by this function. Thus
the output of g_variant_new_*() may be used as an argument.

sr_config_list() also provides a GVariant owned by the caller, to be
unreferenced when done.

sr_config_make() can take a floating reference.

Uwe Hermann 4afdfd4628 Add and use std_session_send_df_header().
This is a small helper function which sends the SR_DF_HEADER packet that
drivers usually emit in their hw_dev_acquisition_start() API callback.
It simplifies and shortens the hw_dev_acquisition_start() functions
quite a bit.

It also simplifies the input modules which send an SR_DF_HEADER packet, too.

This patch also automatically removes some unneeded malloc/free in some
drivers for the 'packet' and 'header' structs used for SR_DF_HEADER.

Uwe Hermann 063e7aef6d Factor out common hw_init() driver code.

Joel Holdsworth bf53457d1d Pass sr_datafeed_packets and payloads with const pointers
This patch marks packet structures and their payloads as const.
This indicates to packet receivers that modifications to these are
not allowed. In general all pointers should be marked const unless
modification of the referenced data is explicitly allowed.

Alexandru Gagniuc e7ed87a469 serial-dmm: Use dummy info struct for rs9lcd parser
The rs9lcd parser, which is used for the RadioShack 22-812 does not use its
*info parameter, and therefore did not have a rs9lcd_info struct declared.

With recent re-factoring of the receive data callbacks, it became necessary to
pass a struct pointer. This made the RECV_DATA macro look like:

- RECV_DATA(RADIOSHACK_22_812, metex14)

giving the wrong impression that the RadioShack 22-182 uses the
metex14 protocol, which is not the case.

Create a dummy rs9lcd_info struct, and correctly identify the parser
as rs9lcd in the RECV_DATA macro:

+ RECV_DATA(RADIOSHACK_22_812, rs9lcd)

Bert Vermeulen 71caaad46b serial: allow for extra rts and dtr options in conn string
Options in addition to the usual "9600/8n1" syntax start with a
slash, and take the form of key=value, where different options are
also separated by slashes. For example:

	"9600/8n1/rts=0/dtr=1"

This sets RTS low and DTR high.

Alexandru Gagniuc a99e0d2a0c ols: Do not randomly probe serial ports
ols driver used to probe a series of available serial ports obtained
by regexp matching of common serial port names.
There are a number of problems with this approach:
1. It will probe all serial devices, including devices that do not
like to be probed, potentially causing them to act up.
2. It will try to probe serial ports which may already be opened in
other applications for other purposes.
3. It assumes the naming of the serial ports is set in stone, and
creates an unnecessary OS-specific list.
4. It produces unnecessary debug output even when an OLS device is
not connected.
5. etc...

Do not implicitly probe serial ports. Only probe the port specified
by the frontend, if any; otherwise, just quit.
Also get rid of all functionality in serial.c which was designed
specifically for random probing.
